Merge actions test data struct and some of the data for the actions API
unit tests. actions_update_app_context_nfu.tests.cpp data has not been
merged because the expected results are different, as it does not do
normalization, unlike actions_get_api and actions_normalize.
Merging of that data could be done, but would require adding extra
fields to each test result, which would make the data considerably
harder to read! Thus I have left it alone for now, just merged the
struct, which is still a win.
